In the rare case that requests exceed the API's 180-second server-side timeout, resulting in `408` or `504` errors, the advice is to retry with exponential backoff and contact support if problems continue.\n"],null,["# Configure timeouts and retries\n\nMany Display \\& Video 360 API methods perform complex operations that might take longer than\na few seconds to complete. Requests to these methods can sometimes exceed\nexpected latency, causing errors on the API or client side. This page lists\npractices for handling issues caused by extended request latency.\n\nIncrease default timeout in client library\n------------------------------------------\n\nA handful of specific methods have been labeled in their reference documentation\nas regularly exceeding expected latency. Other methods could also exhibit\nhigh-latency behavior periodically.\n\nThe default timeout limits for some client libraries could result in errors when\nmaking high-latency requests. Default timeouts for a subset of supported client\nlibraries are:\n\n- **Java**: 20 seconds\n- **Python**: 60 seconds\n- **PHP**: 60 seconds\n\nClient-side timeouts can be avoided by raising these default timeouts. Follow\nthese instructions to adjust the default timeout for your client library during\nruntime:\n**Caution:** The Display \\& Video 360 API has a server-side timeout value of 180 seconds. If a request lasts longer than 180 seconds, the API will return an error. \n\n### Java\n\n1. **Import necessary resources.**\n\n import com.google.api.client.http.HttpRequest;\n import com.google.api.client.http.HttpRequestInitializer;\n import java.io.IOException;\n\n2. **Build function for setting HTTP timeout.**\n\n /**\n * Adjusts HTTP timeout values used by the provided request initializer.\n *\n * @param requestInitializer The {@link HttpRequestInitializer} used to authorize requests.\n * @param newHttpTimeout The HTTP timeout for requests in seconds.\n * @return An {@link HttpRequestInitializer} with modified HTTP timeout values.\n */\n private static HttpRequestInitializer setHttpTimeout(\n final HttpRequestInitializer requestInitializer,\n final int newHttpTimeout) {\n return new HttpRequestInitializer() {\n @Override\n public void initialize(HttpRequest httpRequest) throws IOException {\n requestInitializer.initialize(httpRequest);\n httpRequest.setConnectTimeout(newHttpTimeout * 1_000);\n httpRequest.setReadTimeout(newHttpTimeout * 1_000);\n }\n };\n }\n\n3. **Call function when creating the Display \\& Video 360 API client.**\n\n // Create authorized API client with non-default timeouts.\n DisplayVideo service =\n new DisplayVideo.Builder(\n credential.getTransport(),\n credential.getJsonFactory(),\n setHttpTimeout(credential, \u003cvar translate=\"no\"\u003e\u003cspan class=\"devsite-syntax-n\"\u003ehttp\u003c/span\u003e\u003cspan class=\"devsite-syntax-o\"\u003e-\u003c/span\u003e\u003cspan class=\"devsite-syntax-n\"\u003etimeout\u003c/span\u003e\u003cspan class=\"devsite-syntax-o\"\u003e-\u003c/span\u003e\u003cspan class=\"devsite-syntax-n\"\u003ein\u003c/span\u003e\u003cspan class=\"devsite-syntax-o\"\u003e-\u003c/span\u003e\u003cspan class=\"devsite-syntax-n\"\u003eseconds\u003c/span\u003e\u003c/var\u003e)\n )\n .setApplicationName(\"displayvideo-java-installed-app-sample\")\n .build();\n\n### Python\n\n1. **Import Google API Python client library http module.**\n\n from googleapiclient import http\n\n2. **Update default timeout constant.**\n\n http.DEFAULT_HTTP_TIMEOUT_SEC = \u003cvar translate=\"no\"\u003e\u003cspan class=\"devsite-syntax-n\"\u003ehttp\u003c/span\u003e\u003cspan class=\"devsite-syntax-o\"\u003e-\u003c/span\u003e\u003cspan class=\"devsite-syntax-n\"\u003etimeout\u003c/span\u003e\u003cspan class=\"devsite-syntax-o\"\u003e-\u003c/span\u003e\u003cspan class=\"devsite-syntax-ow\"\u003ein\u003c/span\u003e\u003cspan class=\"devsite-syntax-o\"\u003e-\u003c/span\u003e\u003cspan class=\"devsite-syntax-n\"\u003eseconds\u003c/span\u003e\u003c/var\u003e\n\n3. **Build API service.**\n\n # Build the API service.\n service = discovery.build(\n 'displayvideo',\n 'v3',\n discoveryServiceUrl=discovery_url,\n credentials=credentials)\n\n### PHP\n\n1. **Download and install the Guzzle HTTP library using\n [Composer](//getcomposer.org/).**\n\n composer require guzzlehttp/guzzle:^7.0\n\n2. **Create Guzzle HTTP client, assigning timeout value.**\n\n $httpClient = new \\GuzzleHttp\\Client(['timeout' =\u003e \u003cvar translate=\"no\"\u003ehttp-timeout-in-seconds\u003c/var\u003e]);\n\n3. **Create Google client and assign Guzzle HTTP client.**\n\n $client = new Google_Client();\n $client-\u003esetHttpClient($httpClient);\n\nHandle API timeout errors\n-------------------------\n\nIn rare cases, requests completing complex operations could exceed the\nserver-side timeout of 180 seconds, causing the API to return a `408` or `504`\nerror response.\n\nIf a request responds with either of these error codes, we recommend that you\nretry these requests using the [exponential backoff strategy](/display-video/api/guides/how-tos/upload#exp-backoff).\n\nIf the error persists, reach out to support using the [contact form](/display-video/api/support/contact)."]]
